Description
Liquid Nails Fast is a water-based, high-strength construction adhesive with fast grab and low odour. It has a thick, non-runny consistency and is ideal for adhering timbers and other porous construction materials. Once dry, it has a beige (light tan) finish.
Uses
Liquid Nails Fast has a high initial grab that reduces the need to support joins while the adhesive cures. The grab works best with porous surfaces. It bonds to a wide range of materials including MDF, particle board, timber, plasterboard, styrene foam, masonry, concrete, tiles, ceramics, metals, plastics*, rubber and glass. Faster results occur when at least one surface is porous.
Typical applications include:
- Areas where nailing is not desirable
- Skirting boards, architraves, and cornices
- Wall panelling to masonry
- Styrene foam to metal roofing
Technical Features
- Fast grab – high initial holding reduces slippage on vertical surfaces
- Complies with AS 2329-1999 (Mastic adhesives for fixing wall boards)
- Non-drip formula – does not sag or string between panels
- Bridges gaps and adheres to uneven surfaces
- Low mess – excess can be wiped away with a damp cloth
- No solvent fumes – ideal for indoor projects
- Flexible – withstands thermal movement and vibration
- Heat resistant – maintains bond strength under sunlight
- Paintable when dry
- Easy to extrude in all temperatures
Application Tips
- Use in conjunction with permanent mechanical fasteners except for low-stress applications such as wall panelling or lightweight fixtures.
- Bonds are not water resistant – protect from water if used outdoors.
- Drying time is extended in cold or damp conditions and with non-porous materials.
- Thicker layers take longer to dry.
- Test plastics before use – adheres well to UPVC but not to polyethylene or polypropylene.
- For wood flooring, use solvent-based Liquid Nails instead.
- Satisfactory for fixing sheet flooring to joists with the manufacturer’s minimum nailing specification, but not recommended for bonding sheet flooring to existing or concrete floors.
Technical Details & Performance

Coverage
Approximately 15 metres of a 5 mm diameter bead. Curing time increases with thicker bonds or larger bond areas. Data provided is indicative only and not for design use.
Cleaning
Clean with hot soapy water or a damp cloth while wet. Once dry, remove by scraping or peeling.
*Always pre-test plastics for adhesion suitability.
